I mean he didn’t get 4 concubines willingly, it was well explained that it was power struggle. It was decided as a condition to the marriage with the empress that he was not even planning to love anyway (it shouldn’t have even been Zelda). Don’t get me wrong I absolutely hate the concubines bullshit but it’s not exactly the ML fault.
i don’t know if I’m gonna continue reading this because I just know it’s gonna be a lot suffering for the FL. And I smell the « I run away after doing it and end up pregnant » trope when the « true empress » takes her place.
Pretty sure he didn’t do anything with Catherine. She would have boasted everyone about it if it was the case. They maybe had an arrangement that’s why she was in his office.
